NGlyO – for beta sheet formation
Surprising behavior of NXO-peptides.
Read more
It is a significant property of peptides that oxalo-retro azapeptides have the same donor and acceptor distances and properties for hydrogen bridge formation as a tripeptide fragment and therefore induce beta-sheet formation at this position.
